Scatter plots - non-linear relationship, Advanced Statistics

The scatter plots of SRES1, RESI1 versus totexp demonstrates that there is non-linear relationship that exists as most of the points are below and above zero. The scatter plots show that there many vertical structural breaks clearly visible. There are many outliers that can be seen and are obvious when analyzing these scatter plots. There is no leverage or influential points that are determining the slope of the line of best fit. There is no heteroscedasticity in these scatter graphs which means there is constant variance.
